English Tenses Practice

詳解：The correct answer is 'goes' (simple present) because 'every day' indicates a habitual action. 'Go' is incorrect with third person singular; 'is going' implies present continuous (happening now); 'has gone' is present perfect (recent past).

詳解：'Were watching' (past continuous) is correct because the action was in progress when another action (called) interrupted. 'Watch' is present; 'have watched' is present perfect; 'watched' is simple past, which doesn't show ongoing action.

詳解：'Will have started' (future perfect) is used for an action that will be completed before a future time. 'Starts' is simple present; 'started' is past; 'has started' is present perfect, not future reference.

詳解：'Haven't finished' (present perfect) is correct because 'yet' indicates an action that hasn't happened up to now. 'Didn't finish' is simple past (specific past time); 'don't finish' is present; 'wasn't finishing' is past continuous.

詳解：'Has worked' (present perfect) is correct because 'since 2010' indicates an action that started in the past and continues. 'Works' is simple present (general truth); 'worked' is past; 'is working' is present continuous (temporary).

詳解：'Went' (simple past) is correct for a past habit. 'Go' is present; 'have gone' is present perfect; 'was going' is past continuous (often for interrupted actions). 'Every summer' indicates a repeated past action, best expressed by simple past.

詳解：'Is shining' (present continuous) is correct because 'Look!' indicates the action is happening at the moment of speaking. 'Shines' is simple present (general fact); 'shone' is past; 'has shone' is present perfect.

詳解：'Lost' (simple past) is correct because 'yesterday' specifies a past time. 'Loses' is present; 'has lost' is present perfect (no specific past time); 'was losing' is past continuous, which doesn't fit a completed action.

詳解：'Have gone' (present perfect) is correct because 'this week' is a time period that includes the present, and the action has occurred multiple times. 'Go' is present habitual; 'went' is past (finished week); 'am going' is future arrangement.

詳解：'Will have finished' (future perfect) is correct because 'by next year' indicates a point in the future by which the action will be completed. 'Finish' is present; 'will finish' is simple future; 'finished' is past.
